OK I love the ZL1 and will be one of the first to get one, if they will take my 2010 2ss 625hp in trade. My observation is that the press release states the tires as Goodyear Supercar F2's. Yet the press photos show F1's.

Looking up on Goodyears Website I can not locate any F2's. I see three models of the F1 Supercar tires. They are:

I would like to know if there is an F2 Supercar tire or was this a typo?

Also I would like to know the opinions of fellow members and tire experts on the feasibility of using these F1 Supercar (or the F2s if they do exist) as a better substitute for the stock tires for aggresive spirited street driving.

I have 18,000 miles on my stock tires and I am about to get some CCW sp16a 20 x 10 and 11.5 and may put on the Goodyear Supercar rubber. The runflats appeal to me as that is what is on my Vette and the runflat feature has been useful several times on it.

It's hard to find information on these... THESE are on GT500s, or are an older generation on them?

Goodyear's original Eagle F1 Supercar EMT Max Performance Summer Run-Flat tire has been Original Equipment on Corvettes with the performance handling or Z06 packages since the C6 chassis debuted in 2005. For the 2011 Corvette Z06, Chevrolet has chosen Goodyear's new 2nd generation Eagle F1 Supercar G: 2 RunOnFlat tires as Original Equipment.

However several members of the Tire Rack team did have the chance to experience the new Eagle F1 Supercar G: 2 RunOnFlat during a visit to the Bob Bondurant School of High Performance Driving in Phoenix, AZ. The Bondurant crew outfitted two of their Corvette Z06s with scuffed-in, full tread depth tires to compare back-by-back. The first car wore original Eagle F1 Supercar EMT tires and would serve as our baseline reference, while the second car was fitted with the new Eagle F1 Supercar G: 2 RunOnFlat tires.

First Impressions
After some familiarization laps in a standard C6 Corvette with the Z51 performance package on Eagle F1 Supercar EMT tires, we were ready to compare tires on a pair of the school's bright red 2008 C6 Corvette Z06s. The Z06 brings big brakes, tuned suspension and just over 500 horsepower to the equation - enough to challenge any tire holding it to the ground.

Going out first for a few laps in the car equipped with the original Eagle F1 Supercar EMT confirmed our initial impressions. It's apparent Chevrolet and Goodyear fine-tuned this combination for the C6 Corvette, as car and tire seem to be in sync with each other. Steering response was smooth and linear, turning down to the apex with precision. Overall vehicle balance was good, too, with both the front and rear tires reaching their grip limit at the same time. The Z06's traction control engaged occasionally and predictably, mostly when we were simply too aggressive with the throttle on corner exit.

Then we were back into the pits to switch to the car with the new generation Eagle F1 Supercar G: 2 RunOnFlat. It only took driving into the first turn to realize the new generation tire was working on a whole new level of performance. The most obvious change came in steering response - this car/tire combination feels directly connected to the driver, responding almost instantly to steering inputs. Several drivers commented on how the Eagle F1 Supercar G: 2 RunOnFlat felt more like a dedicated track tire than a street tire. Cornering power at the apex was impressive and perceptibly better than with the original Eagle F1 Supercar EMT. We did not experience as much intervention from the Corvette's traction control system during hard acceleration away from the corners, and braking traction felt sure-footed, too. As a package, the car fitted with the Eagle F1 Supercar G: 2 RunOnFlat felt more connected to the track, resulting in higher driver confidence and quicker overall track speed.

Objective Data
To find out just how fast around the road course the Eagle F1 Supercar G: 2 RunOnFlat was, we put Bondurant's chief instructor Mike McGovern behind the wheel. Mike knows the track, cars and original Eagle F1 Supercar EMT tire like the back of his hand, so any performance differences should become readily apparent. We equipped the cars with our Racelogic DriftBox data acquisition unit to capture lap times and performance data.

First, Mike made a baseline run on the original Eagle F1 Supercar EMT, starting with 2 warm up laps followed by a tight group of 4 timed laps, averaging 54.25 seconds with a fastest lap of 53.90. Switching to the Eagle F1 Super Car G: 2 RunOnFlat he again warmed the tires and then put in another group of 4 test laps. In his first ever hot laps on the new generation tire, Mike's 4-lap average was 52.65 seconds with a fast lap of 52.40, or 1.50 seconds faster than the original Eagle F1 Supercar EMT. Wow!

A look at the data from the fastest lap on each tire shows where the new tire's performance comes from. The graph's red trace of the Eagle F1 Supercar G: 2 RunOnFlat is always beyond the trace of the original Eagle F1 Supercar EMT shown in black. With the Eagle F1 Supercar G: 2 RunOnFlat Mike was able to accelerate sooner, brake a little later and carry more speed through the corners at every turn and down each straight.

Summary
The original Eagle F1 Supercar EMT showed it's still a good design for the Corvette and will continue to be used by Chevrolet as the Original Equipment tire for performance handling package cars. The new Eagle F1 Supercar G: 2 RunOnFlat raises the bar, and will initially be available in limited sizes for key applications. In the rarified air of modern supercars, Goodyear's new Eagle F1 Supercar G: 2 RunOnFlat breathes easily, showing just why Goodyear chose to call this tire "supercar." It really is the next generation super tire for today's supercars.

I am optimistic this car will be a flawless performer. Specially-developed versions of the G2 Supercars will do much to help.

With the new power should come with a new car option.
Tire options. Drag radials if you want. like NT05Rs or Eagle SS if they have to stay with goodyear.
option for stickier racing tires for road course people. like PZero Corsa system (dont think that make PZero Corsa anymore)

I got my 2010 2SS/RS loaded with all the options, sans the 21" wheels, and found that my 426hp was slower than my 588lb lighter 375hp 2001 Vette. So I fixed that with installing the TVS2300 maggie, Hurst shifter, American Racing Headers, Noweeds exhaust cutouts to stock muffler, Cold Air Inductions CAI, and fine tuned it all with Jannetty Racing's tuning.

I call it a sleeper because it looks and sounds completely stock if I want it to.

The 2010 SS is a great platform to modify and enjoy the hidden potential that is waiting to be freed.

The 2012 ZL1 has so many improvements to the "Bones" of the car that the bang for the buck$ can't be added to an "older" 2010 or 2011 model in add ons to merrit not buying one. In other words, You can't build one and get the same performance or options that Chevy has included into the base guts of this magnificant machine.

This is a much better platform to modify than the 2010, 2011. It already has twin disc clutch, heavier duty drivetrain all the way to the variable magnetic shocks and lighter wheels, a factory 1900 supercharger, dual power seats, etc.. the list goes on and on and includes a warranty.

I may not modify it right away as Chevy has done their homework and I think they have it tuned to put the power the pavement better than mine. Yes I have more power but I am still running the stock suspension and hooking up is not as effective as their ZL1 is,I am sure.

I was going to add either Pedders or Pfadts best suspension system but I decided not to now because of the ZL1. I do want to try and find the ZL1 rims and tires and replace mine with those if possible.

The ZL1 changes everything. And that is good. It just keeps getting better and we get the chance to own one.

We get a chance to own one of the best made and best bang for the buck hotrods ever, and if not satisfied, we can swap a pulley and increase its hidden potential anytime we feel like it.

I hope that they do not put the Eagle F1 that are on the gt500 because those are pieces of crap, and they look different than the gt500 f1. So that is a very, very good thing.

The F1's on the 2010 GT500 and the standard 2011 GT500 are rock hard hockey puck rubber. I replaced mine with Hankook evo V12's (in the stock sizes) and that was a HUGE upgrade, straight line traction and cornering grip both improved dramatically.
The 2011 GT500's with the SVT-PP have the much better F1 G2 tires. But they are still pretty hard and weak for straight line traction.

I heard the Goodyear F1 and F1 G2 require preheating or just some hot laps before usage... The Motor Trend tester Randy Pobst commented on that as well. When they are cold they are no good.

I hear Michelin PS2's and Pirelli P Zero's are the best non-comp performance tire right now but cost a good bit...
